The goal of this trial is to demonstrate that new treatments are as effective as a reference triple-agent regimen in driving plasma viral load below the detection limit early during treatment (16 weeks). These simplified treatments involve fewer tablets and intakes, fixed-dose combinations, and also radically new strategies such as boosted protease inhibitor and tenofovir.

The efficacy of antiretroviral treatments in sub-Saharan Africa has been demonstrated in cohort studies and pilot trials. The treatment regimens tested in these studies were derived from those used in pre-marketing trials conducted in industrialized countries.

However, the choice of antiretrovirals for national programs in poor countries is largely based on drug availability through the Access program, together with cost and supply considerations, rather than on field evaluations of recommended strategies.

Concomitantly with the development of antiretroviral access programs in the southern hemisphere, first-line treatments in industrialized countries have tended to become simpler, thereby improving their convenience and reducing the incidence and severity of their adverse effects. These simplified treatments involve fewer tablets and intakes, fixed-dose combinations, and also radically new strategies such as boosted protease inhibitor and tenofovir. These simplified strategies are being extensively evaluated in industrialized countries.

Long-term economic benefits will be a determining factor in the adoption of these strategies by poor countries.

Methods:

We will conduct a phase-III unblinded randomised trial focusing on the early virologic efficacy, tolerability and immuno-virologic efficacy of four simplified antiretroviral regimens given for 96 weeks to previously untreated HIV-1-infected patients in Senegal and Cameroon. The following four simplified treatments will be tested: TDF/FTC/NVP, LPV/TDF, TDF/FTC/AZT and TDF/FTC/EFV. The required number of patients (n=120) is compatible with the short-term recruitment capacity of two clinical investigation centers in Senegal and Cameroon.

Objective:

The goal of this trial is to demonstrate that these new treatments are as effective as a reference triple-agent regimen (TDF/FTC/EFV) in driving plasma viral load below the detection limit early during treatment. The principal objective is to identify simplified treatments capable of driving viral load below 50 copies/mL at week 16 in at least 50% of patients. If successful, the initial treatments will be continued and re-assessed at 96 weeks.

Study design:

120 patients previously unexposed to antiretroviral drugs will be recruited over a one-year period in two treatment centers in Dakar (Infectious Diseases department of Fann University Hospital) and Cameroon (Yaounde Military Hospital and Principal Hospital)

Expected results:

This study is fully in keeping with WHO/UNAIDS recommendations on antiretroviral treatment simplification in poor countries. These new treatments must be evaluated in the countries concerned, given the often very advanced stage of HIV disease at diagnosis, intercurrent health disorders, and local socioeconomic conditions.

This trial is not designed to compare these new treatments with one another, but rather to select the most promising treatments for future use. These preliminary results will help with the choice of treatment strategies for cohort studies and large-scale randomized trials.
